The Effects of Galaxy — Galaxy Interactions on Nuclear Activity
The notion that galaxy — galaxy interactions do affect the properties of galaxy nuclei is not new. The earliest indications come from surveys of the radio continuum emission from spiral galaxies. Sulentic (197...

Nuclear Activity: How Irritating Are Neighbours?
Many observational studies in the last decade have strongly suggested that galaxy - galaxy interactions do affect the properties of spiral galaxies, in particular the properties of their nuclei. The first indi...

HST/FOS UV-Spectroscopy of Weak Radio Galaxies At z = 0.1-0.6
We present HSTFOS-spectra for 6 early-type weak radio galaxies with 0.08 < z < 0.53 and V = 17-21 mag. Most of these have deconvolved r -1/4 HST light-profiles out to z < 0.6. Lyman-α emission has...

Stellar Populations in Mixed Pairs of Galaxies
The interpration of the interaction in galaxies is simplified in mixed pairs (E+S) because most or all of the cold gas can be traced to an origin in a single galaxy (S). We used spectroscopy, imaging, far-IR, ...

Distribution and Content of Dust in Overlap** Galaxy Systems
We present a progress report on our program to determine the opacity of spiral disks directly, rather than statistically, by imaging foreground spirals partially projected against background galaxies. The non-ove...

Hst Observations of Abell 2125: Radio Emission and the Butcher-Oemler Effect
We have surveyed more than 40 Abell clusters at redshifts z ≥ 0.2 with the VLA at 20cm down to radio powers of P20cm ~ 1022 W Hz-1. For P20cm > 1023, the radio luminosity function (RLF) is dominated by nuclear/AG...
